Abstract
BACKGROUND
Anaplastic thyroid cancer (ATC) is a rare but aggressive type of thyroid carcinoma. BRAF V600E-mutation, which is found in 10%-50% of ATCs, is associated with poor prognosis. A recent clinical trial reported a substantial clinical benefit of concomitant treatment of dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) for treating BRAF V600E-mutant ATC. However, reports on patients with ATC treated with this regimen following surgery are lacking.
CASE SUMMARY
We report the case of a 63-year-old female patient diagnosed with BRAF V600E-mutant ATC. Following three surgeries—total thyroidectomy, total laryngectomy, and neck dissection—she was diagnosed with lung metastasis during follow-up. The metastatic ATC was successfully treated with dabrafenib and trametinib. The patient achieved a complete response at the 32-mo follow-up.
CONCLUSION
Adjuvant chemotherapy with dabrafenib plus trametinib is efficacious for treatment and prevention of recurrent ATC with BRAF mutation following surgery.
Core Tip: Anaplastic thyroid cancer (ATC) is a rare but aggressive type of thyroid carcinoma. The BRAF V600E-mutation, found in 10%-50% of ATCs, is associated with a poor prognosis. A recent clinical trial reported a substantial clinical benefit of dabrafenib (BRAF inhibitor) plus trametinib (MEK inhibitor) in treating BRAF V600E-mutant ATC. This report highlights the therapeutic potential of dabrafenib plus trametinib as an adjuvant chemotherapy to treat and prevent the recurrence of ATC confirmed with BRAF mutation following surgical resection.
